A four star rating is based on the size of the box as seen by the dents in the cardboard from the motor shafts and an end of the DuPont wire that did not have its cover In my opinion, it doesn't look very professional. My intention is to test the boards. They appear to be in good condition. It is safe to assume that they all worked as intended, even if I fail to update my review. Taking into account the price, I'd say it's a great buy.
The other 2 were broken (drive shaft not turning at all and making fearful noises), and the seller did not respond to contacting them. The rest of them worked just.
It is important to mount them directly to the PLA because they run a bit warm.
A great value for the money. Ben and I followed each other. I am Akrin. Where is www. com/? My Raspberry Pi 4 was used to test the six motors and their driver boards if p=9768. I am very happy with all of them! If you apply too much torque or try to run them too fast, they will slip, so don't.
